Application filed April 16, 1926. Serial N6. 102,430.

' This invention relates to cotton harvesters and is designed more especially as an improvementeupon the structure disclosed in my co-pe'nding application filed August 13,

1925, Serial No. 50,077.-

One of the objects of the invention is'toc provide a machine which can be drawn along rows of standing plants, there being simple and efiicient means for beating the plants so as to separate the cotton bolls therefrom and bringthem into the path of an aircurrent which acts to carry the bollsto separating mechanism constituting a part of the 1113- chine.

A further object is to improve upon the separating mechanism sov as -to increase its efficiency by effecting an almost complete separation of the fibers from thetrash.

lvVith the foregoingand other objects in.

view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed itbeing understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what'is claimed without departing from the SpHll/Of the invention.

I In the accompanying drawings the preferred form of the invention has been shown. In said drawings, 7

through the separating mechanism.

Referring to the figures'by characters of reference 1 designates a'vehicle body provided with supporting wheels 2 and this structure is adapted to be propelled by any 7 suitable means 7 provided for; that purpose.

I Suspended from the body'is a housing 3'having its bottom portion curved transversely as at 4 so as to present a convex surface extending longitudinally of the housing. A longitudinally extending plant receiving opening 5 is formed in this bottom portion 4 and the ends of the housing are formed withupwa'rdly extending openings 6 regis tering with the ends of the opening 5. VAdjustably mounted upon the ends of the housing 3 and across the openings 6 are cross strips 7 which can beheld to the end walls by bolts 8 or the like insertable intoopenings is an enlarged view partly in 9 arranged in parallel series. In these cross str ps is journaled a longitudinal shaft 10 these blades will be moved successively across the-lower portion. ofhousing 3 close to the bottom opening 5. I

Arranged above the housing 3 is a blower casing 13 the outlet of which opens into a downwardly extendingfiue 19 This flue is built into one side of andextends throughout the length of the housing 3, the trans verse of the area of the flue gradually diminishing toward the lower end and the said flue being provided with an outlet 20extending longitudinally of the housing closeto one side of the opening 3. Thus it will be seen that, during the operation of the blower 21 astrong current of air will be directed downwardly within the flue 19 and will be of the housing, this plate and the wall 22 converging upwardly and providing-an inlet 24 to the housing 2510f the separating mechanism. In this houslng are arranged two superposed cylinders 26' and'27 having radial teeth 28 upon their peripheries. "The walls of the housing are concentric with; and supported close to the paths of these teeth or spikes, the outer wall of said housing being preferably formed of a foraminous material '29,ias'shown. The top 30of the housing 25 is extended laterally beyond the uppermost c'ylinder 27 and constitutes the top of an extension housing 31. In the lower portion of this extension housing are superposed troughs 32 and'33, there being a worm 34 mounted for rotation in the trough 33and a worm 35 mounted for rotation in the trough 32; A shaft 36 is jour naled in the extension housing 31 and supports a drum 37 on the periphery of? which are formed annular series of saw teeth 38. This drum is provided with a concave'39 extending from the lowertrough 32 upwardly partly around the drum 36 to :1 ridge it) where it merges into a pocket tl having an outlet opening 12 at the rear end thereof. A rotatable brush 43 is arranged within the extension housing 31 above the ridge so as to extend across the inlet 44 of the pocket 42. This brush is designed to engage the teeth 38 so as to deft fibers therefrom and 'direet the1n-into the pocket etl. A rotatable heater in the fornnof a cylinder 45 having peripheral longitudinal ribs LG is journaled *above the (1111111 37 hetweenthebrush 43 and the *upper wall 34. A guard plate &7 is extended downwardly from the top '30 and serves todefiect downwardly toward the wall B t all materiel thrownolt of theupper cylintler 27.

i The fine 19 has a brunch iluc 48 extending from the upper portion thereo'tand opening into the forward end ot the pocket 41. Fonthe purpose of driving the -arious parts or the separator an .ihle ineehm hism may be utilizetl. In the structure it lustrated n nieindrire shaft 19 is extended from {in engine/"5O and-has a pulley 51 which transmits inotionthroughn belt 52 :0 a pull- 'ley ol seeuredto theshait LU. Another pal ley is secured to the shaft 49 end is adapted totransrnit motion through a helt to a pulley 06 secured to the shaft 57 ot the blower Anotherpullej fiS carried by the shaft- 57 and transmits niotion througha belt 59 ton pulley 60 secured to the shaft 36. A sprocket 61 can alsobe se- -eured tothis-shajt 36and drires anendless ehain tfi. This chuinengeges a sprocket (l3 on th'e shafted ofeylintle'r 96, u sprocket 65 on shaft 66 M cylin'derEZ'T, sprochets tfiand 68 connected to and rotatable with the worms 134 and35, a sproehet69 secured to the ShaftTO o't =the beziter an idler sprocket Tip-and e sprocket 72 secured to the shatt'i'l oit bruslr ttl.

From theforegoing it will be apparent that tlnring the operation of the machine the various purts will be operated Sll1'ltiltttneously in the direetions indicated lay the arrowsandthe action will he as follows:

The standing plants will he received within the"openinp ties the machine moves forwardly zind the rotating heaters orhladrs 13 will strilte the plantsundhnock the bolls from them. During this rution a strong sheetet air under pressure being delirered throughout the length of the housing "transversely of the openingo so that the do taehed bolls will be caught in the hlust and driven laterally and upwardly into the throat or inlet "2i it of the separating nieehunisnr. -l-[ere the bolls will be siu-eessiretr acted upon by the teeth or spikes on the eylinders 26 and lTpthe hulls and trash being: dragged over the screen 29 end the small particles being delivered throughthe screen.

within the lowentronp h 'tor deliri The fibers however, will be thrown oil' of the upper eylinder bycentritugal force and come against the guard plate =19 which will detleei them with any trash co niningled therewith into the upper trough 33. The worm in this trough will carry the material in the direction indicated by the arrow and against thehmrhnd will. tendto draw the material along a line parullelwith the axis of rotation of the drum 3?. Thus the tearing action will be very ellieient because not only will the suns engage and pull uponthe fibers but, :it the seine t.irne,the worm will dra the libers tinnsversely oi the pathso't the teeth (vi the saw. Trash separated from the libers during this ope'ation will :ta ll into the lower trough and be carried rearwardly by the rotetmg worn1'35. As
